Sony Bravia keeps disconnecting from Wi-Fi — router, TV settings, app and DNS issues

Technician avatar Technician
Hey! We’ll track down why your Sony Bravia keeps disconnecting from Wi-Fi and stop the TV from dropping the internet every few minutes. A few quick details so we don’t guess:
• Exact Sony Bravia model (e.g. X90H, X85J, A80J, X90K) and roughly which year you bought it?
• Is it an Android TV or Google TV (you’ll usually see that on boot), and are you using Wi-Fi or a wired LAN cable?
• What happens when it disconnects: message like “Wi-Fi has been disconnected”, “Could not connect to the network”, or error codes such as 1107, 2200, 2123?
• Does the Wi-Fi connection drop only on the Sony Bravia, or do other devices (phone, laptop) also lose internet?
The more we know, the faster we can fix a Sony Bravia TV that keeps dropping its internet connection instead of just rebooting things randomly.
Customer
I’ve got a Sony Bravia X90J on Wi-Fi. For the last week it keeps disconnecting from the internet while I’m watching Netflix or YouTube. A banner pops up saying “Wi-Fi has been disconnected” or sometimes “Error 2200” when I try to reconnect. My phone and laptop stay online on the same network, it’s only the TV that drops.

Got it — very classic Sony Bravia keeps disconnecting from Wi-Fi during streaming case.
When this happens, it’s usually one (or a mix) of these:
• The router changed settings (new channel, band steering, DNS, QoS) and the Bravia Wi-Fi driver doesn’t like it.
• The TV’s network stack glitched after an Android TV / Google TV update and starts dropping the connection even though the signal is strong.
• DHCP or DNS is flaky, so the TV keeps losing its IP address or can’t look up servers → apps show network error or buffer.

We’ll:
1) Check the Wi-Fi signal and band your Sony Bravia is using (2.4 GHz vs 5 GHz).
2) Reset only the TV’s network settings and reconnect cleanly, with a reliable DNS server.
3) Lock in some router options and, if needed, give the TV a reserved IP so it stops dropping out.
If the Sony Bravia keeps disconnecting from internet even on Ethernet, we’ll look at firmware and a deeper TV reset.
Customer
The router is a dual-band mesh system. The TV is on 5 GHz, about 6–7 meters away. Signal shows “Good” in the network menu. It will work fine for like 20 minutes, then I get buffering, and suddenly it says “Wi-Fi disconnected, check your network settings”. Sometimes it reconnects on its own, sometimes I have to go into settings and select the Wi-Fi again. It’s annoying because the Sony Bravia loses connection almost every day.

Mesh + 5 GHz can be great for speed, but some Sony Bravia TVs keep dropping Wi-Fi when they’re right on the edge of range or being bounced between mesh nodes.
Step 1 — Check how stable the connection really is on the TV
1) On the Sony Bravia, go to Settings > Network & Internet (or “Network” on older models).
2) Select your Wi-Fi network and look at Signal strength and connection speed.
  • Aim for 3–4 bars; if it’s 1–2 bars or “Poor”, the TV will disconnect under load.
3) If the mesh lets you, temporarily connect the TV to a nearer node, or move the nearest node a bit closer to the TV and retest.

Step 2 — Try the “other” band as a test
• If it’s on 5 GHz now, try connecting the TV to a 2.4 GHz SSID for a while (often called HomeWiFi_2G or similar). 2.4 GHz is slower but usually more stable through walls.
• If you have a separate SSID for the 5 GHz band, avoid “band steering” for the TV for now — we want it to sit on one band without hopping.
Once we know whether the Bravia disconnects on both 2.4 and 5 GHz, we’ll reset the TV’s network stack so it stops remembering bad settings.
Customer
I tried 2.4 GHz and it still drops, just a bit less often. Other devices on both bands are totally fine. The TV remembers the network name and password, but sometimes when I run the network test it fails on “locating server” and gives 1107 or 2200. Does that mean DNS or something like that? I just want the Sony Bravia Wi-Fi connection to stay stable so streaming works.
Technician avatar Technician
Exactly — Sony Bravia network error 1107/2200 usually points to DNS or a confused network stack, even if the Wi-Fi signal is fine.
Step 3 — Reset only the TV’s network settings and reconnect cleanly
1) On your Bravia, go to:
  • Settings > System > About > Reset > Network reset (Google TV / newer Android TV)
  • or Home > Settings > Network > Advanced > Network reset (older Android TV)
2) Confirm the network reset. The TV will drop off Wi-Fi and forget saved networks.
3) After it restarts the network, go to Settings > Network & Internet > Wi-Fi, select your main SSID, and enter the password.
4) Before saving, choose Advanced options and set DNS to manual (e.g. 8.8.8.8 and 8.8.4.4), then reconnect.

This often stops a Sony Bravia TV from disconnecting repeatedly because it rebuilds all network parameters and uses a clean DNS instead of whatever glitch it was stuck on.
Customer
I did the network reset and set Google DNS. It worked fine last night, but today Disney+ froze and kicked me back out with a “check your internet connection” message, then the TV said it wasn’t connected again. When I ran the connection test it passed to the router but failed the internet step. My ISP says the line is fine. Could my router settings be making the Sony Bravia drop the internet connection?
Technician avatar Technician
Yes, certain router features can make a Sony smart TV keep disconnecting from Wi-Fi, even when other devices seem fine.
Step 4 — Tweak router settings for the Sony Bravia
In your router or mesh app, look for:
• DHCP lease time: set it to at least 24 hours so the TV isn’t constantly renewing and dropping its IP.
• Create a DHCP reservation for the Bravia’s MAC address, so it always gets the same IP address.
• Turn off features like “AP isolation / client isolation” or strict guest mode if the TV is on a guest network.
• On 2.4 GHz, try a fixed channel (1, 6 or 11) instead of “Auto”, and keep channel width at 20 MHz.

If your mesh has options like “Airtime fairness”, “Wi-Fi Multimedia (WMM) power-save”, or very aggressive power-saving, try disabling those just for a test. Bravia TVs can be picky and disconnect from Wi-Fi when routers get too clever.
Customer
I set a reserved IP and turned off some of those options. It improved, but one weird thing: I tried a wired LAN cable, and even on Ethernet the Sony Bravia still loses the network occasionally and shows error 2200 during tests. Does that point more to a TV firmware problem than Wi-Fi?
Technician avatar Technician
If the Sony Bravia disconnects even on a wired connection, that’s a big clue it’s not just Wi-Fi — it’s software or how the TV talks to the network in general.
Step 5 — Update TV firmware and adjust advanced network options
1) With the TV temporarily online, go to Settings > System > About > System software update and check for updates.
2) Turn off “Automatic software download” for now — some users see frequent disconnects right after certain updates, so we want control.
3) Under Network & Internet > Advanced, if there’s an IPv6 toggle, try turning IPv6 off to see if stability improves.
4) Make sure power saving modes like “Wi-Fi on standby” or aggressive eco modes aren’t turning off the network while you’re watching.

If a bad firmware build is causing the Bravia to lose internet connection randomly, a full “initialize” reset usually clears it — we’ll keep that as a last resort.
Customer
I updated the software and turned off IPv6. It’s better, but once in a while the TV still signs me out of apps and says “no internet connection” until I reboot it. Would a full factory reset help, or is that overkill? I don’t really want to set up all the apps again unless it will finally stop the Sony Bravia disconnecting from Wi-Fi.
Technician avatar Technician
Good question. When a Sony smart TV keeps disconnecting from the internet even after network resets and router tweaks, a factory reset is usually what finally clears deep glitches.
Step 6 — Decide if a factory reset is worth it
Do a full reset if:
• The TV loses its network daily or multiple times per session.
• Both Wi-Fi and Ethernet connections show similar random drops.
• Network tests intermittently fail with 1107/2200 even though other devices are rock solid.

If that matches your case, a full reset is worth the hassle because it gives the TV a fresh start and often stops a Bravia that keeps dropping Wi-Fi after an update or router change.
Customer
Okay, I think it’s bad enough that a reset might be worth it. What’s the proper way to factory reset a Sony Bravia that has Wi-Fi issues? I’ve seen different instructions online, some mention holding power buttons on the TV itself.
Technician avatar Technician
There are two main ways, depending on model. We’ll use the menu method first; the button combo is the backup.
Menu factory reset (most Google/Android Bravia)
1) Go to Settings > System > About > Reset (or “Device Preferences > Reset” on older Android TVs).
2) Choose Factory data reset → “Erase everything”. The TV will reboot and run through the first-time setup again.
3) When it asks for network, connect to your preferred 2.4 or 5 GHz SSID, and again use manual DNS if possible.

Hard reset using TV buttons (for stubborn cases)
• With the TV off, press and hold the power and volume down buttons on the TV (not the remote), then plug it in while holding until the logo appears. Release and let it complete the reset.

After this, a Sony Bravia that kept disconnecting from Wi-Fi usually behaves like new, especially with the router tweaks and reserved IP we already did. We can walk through the exact path for your model live in chat if you’d like.
Customer
I did the menu factory reset, reconnected it to Wi-Fi with manual DNS, and kept the reserved IP on the router. So far the Sony Bravia stays connected — no more 2200 errors or “Wi-Fi disconnected” messages while streaming. Looks stable now, thanks!
Technician avatar Technician
Summary: when a Sony Bravia keeps disconnecting from Wi-Fi, first stabilise the router (band, channel, DHCP lease), then reset the TV’s network settings, reconnect with reliable DNS and give the TV a reserved IP. If both Wi-Fi and wired LAN drop or you see recurring Bravia network errors 1107/2200, updating firmware and doing a full factory reset usually clears the problem. Not sure which menu or router option applies to your setup? Open the chat and an expert will walk you through it step by step.

Quick answer: the accepted fix

Accepted fix when a Sony Bravia keeps disconnecting from Wi-Fi: reserve an IP for the TV on your router, reset the TV’s network settings, reconnect it to a stable 2.4 or 5 GHz SSID using reliable DNS, then update firmware. If network errors (1107/2200) continue on both Wi-Fi and LAN, perform a full factory reset and set the connection up from scratch.

Why Sony Bravia disconnects from Wi-Fi or the internet

Most cases where a Sony Bravia TV keeps disconnecting from Wi-Fi come down to a mix of network and software issues. Router updates can change the Wi-Fi band, channel, or DNS, making the TV’s Wi-Fi driver unstable. Mesh systems may steer the Bravia between nodes so the Wi-Fi connection drops under load. On the TV side, Android/Google TV updates sometimes corrupt cached network settings, causing error codes like 1107 or 2200 even when other devices are fine. Fixing both the router (band, channel, DHCP) and the TV (network reset, firmware update, factory reset if needed) usually stops the Sony smart TV from losing its internet connection.

How to test if your Sony Bravia connection is really fixed

After changes, leave your Sony Bravia streaming (Netflix, YouTube, Disney+, Prime Video) for at least 30–60 minutes. If the Bravia Wi-Fi connection stays active with no “Wi-Fi disconnected” pop-ups, and the built-in network test passes both router and internet checks several times in a row, your setup is likely stable. Also try switching apps and turning the TV off and on again: if it reconnects instantly and doesn’t show errors 1107 or 2200, your Sony Bravia internet connection dropping problem is probably solved. If disconnects only happen at certain times of day, interference or ISP congestion may be involved.

Sony Bravia keeps disconnecting — quick troubleshooting tips

Most cases are fixed by cleaning up router settings and resetting the TV’s network.

Quick path: check your router’s band, channel and DHCP lease, then give the Sony Bravia a reserved IP address. On the TV, run a network reset, reconnect to a stable 2.4 or 5 GHz SSID, and set manual DNS. Update the TV firmware and disable overly aggressive power-saving or Wi-Fi options. If your Sony Bravia still keeps dropping Wi-Fi or LAN with error 1107/2200, back up any important app logins and perform a full factory reset so the TV starts fresh.

FAQ

Why does my Sony Bravia keep disconnecting from Wi-Fi?

Common causes include weak Wi-Fi signal, mesh or router features like band steering, short DHCP lease times, buggy DNS, or corrupted network settings after an update. Resetting the TV’s network settings and adjusting router options usually stops a Sony Bravia TV from dropping Wi-Fi.

Is Wi-Fi or Ethernet better for Sony Bravia?

A wired Ethernet connection is usually more stable for Sony Bravia, especially for 4K streaming. If you must use Wi-Fi, place the router or mesh node close to the TV, use the band with the best signal (often 5 GHz nearby or 2.4 GHz through walls), and avoid frequent SSID changes.

How do I stop my Sony Bravia from losing internet every day?

Give the TV a reserved IP address in your router, set a longer DHCP lease, reset the TV’s network settings, and reconnect using a stable SSID and reliable DNS. Update the TV firmware and disable aggressive power saving or Wi-Fi options that can turn the network off while in use.

When should I factory reset my Sony Bravia because of Wi-Fi issues?

If your Sony Bravia keeps disconnecting from internet on both Wi-Fi and wired LAN, throws recurring errors like 1107 or 2200, and a network reset plus router tweaks haven’t helped, a full factory reset is usually the fastest way to clear deep software glitches.
